DMG 272 says that "magical healing" can remove a limp, heal an internal injury, or mend a broken rib. Since these are considered to be "Lingering Injuries" it seems crazy that a simple "Cure Wounds" would end the condition. (Of course, I could be wrong).
So what does the term "Magical Healing" mean? Is it any magical effect that restores Hit Points? Do magical potions count?
